My computer currently does not have any network adapter so that there were no
network HW to configure, and network configuration resumed to choose a
hostname.

xserver-xfree86 configuration selected 'IntelliMouse' protocol for my mouse
(whithout asking me) whereas the only working protocol for it is 'ImPS/2': I
had to modify /etc/X11/XF86Config-4 by hand, so that we can't say that
everything worked "out of the box".

That's all folks,
Lionel.

Hi Lionel
As this isn't a d-i problem assigning it to package "xserver-xfree86".
